On that day, (this was also around the time Rivenguild started getting massive amounts of traffic) the Riven Lyst was mail bombed. Thousands of letters were sent to the Lyst by a malicious hacker, filling many e-mail boxes to the brim. Traffic was effectively cut off.
Leading up to this event, this hacker (who called himself the "joker") also sent spoofed e-mails from Rand Miller, and at one point, announced the "death" of RAWA. This prompted an interesting response from RAWA, who was quite surprised by this annoucement. This letter and more can be found here.
RAWA, on March 27, 2001, 8:32 PM, said:
Well, it's been an interesting afternoon.
A phone call from Gordon alerted me that my day wasn't going as well as I had thought it had been. I'm sure getting a second opinion about such things is a wise idea; but as far as I could tell, I seemed to be alive.
Gordon seemed to agree, so we tentatively concluded that the rumor was false.
Until I have enough evidence to the contrary, I will continue my duties as Cyan's D'ni Historian.
With thanks for all your thoughts, concerns, and support,
D'ni Historian (still)
After these attacks on the Lyst, it was debated what was to be done next. Gordon and Doug (Doug had been hired by Cyan a while before this) knew that the service the Lyst was using at the time was not a good defense against attacks. Also, Gordon and Doug were very busy, and did not have the time or the resources to maintain the Lyst. So, they disbanded it a few days later. Soon after this was the fall of Rivenguild, leaving the thriving fan community in disarray, two of its biggest congregation centers gone. (NOTE: MystCommunity and a few other forums are what ended up replacing Rivenguild.)
This was not the end of the Lyst, however, Aquila and Lehsa, two dedicated Myst fans, saw fit to keep the Lyst going. They worked hard behind the scenes, getting the old community back together, and eventually opening up the Lyst anew to any and all Myst fans. The Lyst (which dropped the "Riven" from its title in its second incarnation) is now abuzz once again with speculation. It is also the place where RAWA, not dead as once claimed, is probably the most active.
